Description

From the listing uploaded by “apps”.

Use the magnetic field sensor on your phone to take EMF readings. Works like a 3 axis EMF meter. Displays EMF in milli Gauss (mG) or micro Tesla (uT). Uses include ghost hunting, paranormal research, finding sources of EMF radiation, monitoring EMF levels, and/or curiosity. Instructions for use: Preferences can be found by pressing the menu button. Many display options are available to customize what is on the screen. The range on the meter can be changed in the options or by sliding your finger up or down on the screen. The left side of the screen adjusts the minimum, the right side adjusts the maximum. You can lock or unlock touch adjustments through the menu. Custom color values can be set for the text. Sound can be enabled and customized in preferences, default is off. This will play a tone at a rate determined by the EMF reading, similar to a Geiger counter. More detailed Instructions are available from the menu within the app. Added Features in Paid Version: Full Graph functionality Baseline Mode Auto Ranging Function No Ads This app was designed to be lightweight, fast, and free of gimmicks.

EMF Sensor Free APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the EMF Sensor Free APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is b6603afb92c3148715e3d238ac454ee6.
